4UAD Threadlock Blue

Removable Threadlocker

The 4UAD Blue Threadlock is a great medium strength threadlock component. It comes in a handy pen that makes applying it to threads and hard to reach places a snap.

Simply remove the cap, press a couple of times and apply a small drop of the blue bonding agent to the item.

With precise dosage system, the Blue Threadlock pen will last a long time in the workshop and avoid a mess of glue.

A threadlock is important to prevent screws from falling out over time. Most common usage is in gearboxes and especially the motor screw. As a long time tech, I can testify that it is _mandatory_ to use a light-medium threadlock on the motor adjustment screw, to avoid it backing out over time.

This blue threadlock is also vital for gas blowback pistols and rifles. As many airsoft GBB's use weaker materials than their real counterparts, they cannot have screws torqued with the same strength, and thus needs a threadlock agent to secure the screws against long term blowback vibration.

The threadlock is removable with force and/or heat, but please be careful with how it is used.
Where to apply the threadlock, and in what amount, is estimated on an individual airsoftgun basis. Using it on tiny, long screws or on plastic threads could cause issues with the removal if needed.

Feel free to inquire on our various social media platforms about how to use it, or watch the youtube videos for additional information.
